Climate Change Presentation
The document outlines the key points of a presentation on climate change including: what factors influence climate (sun output, earth orbit, greenhouse gases); evidence it is occurring through observed effects on snow/ice and ecosystems; reasons to care such as impacts of temperature rise on health and coastlines; how scientists are very sure that warming is caused by human activities; and potential actions that can be taken to reduce greenhouse gas emissions at both societal and individual levels.
Climate Change in The world, Effect, Causes, Action.
This document summarizes climate change, its causes and effects, and actions that can be taken. It defines climate change as long-term shifts in weather patterns primarily driven by human activities like burning fossil fuels. Some effects of climate change discussed are hotter temperatures, more severe storms, increased drought, rising sea levels, and more health risks. The causes of climate change outlined include generating power, manufacturing, deforestation, transportation, food production, and overconsumption. The document suggests actions individuals can take to reduce their impact such as saving energy, using less transportation, eating less meat, reducing waste, and switching to renewable energy sources.

This document discusses global warming and its causes and impacts. It explains that global warming is caused by human activities like burning fossil fuels which release carbon dioxide into the atmosphere. Burning coal and driving cars are two major sources of carbon dioxide emissions. If left unaddressed, global warming will lead to more extreme weather, rising sea levels, and other serious consequences. International cooperation is needed to implement policies that reduce greenhouse gas emissions and mitigate the effects of climate change.

Sadra Sepehri D (2)
Global warming is caused by human activities that release greenhouse gases like carbon dioxide into the atmosphere. Burning fossil fuels for electricity, transportation, and industry are major contributors. As greenhouse gas levels rise, more heat is trapped near Earth's surface, leading to increased global temperatures and more extreme weather. To reverse global warming, countries need to transition to renewable energy and cleaner transportation while reducing carbon emissions through international cooperation and policy changes. Impacts are already occurring like stronger hurricanes, rising sea levels, and more frequent heat waves.

What are we doing to our climate? What is it doing to us? What can we do?
OVERVIEW
I will be introducing you to ECONOMIC, ECOLOGICAL, and TECHNOLOGICAL ISSUES.
¥ Climate change is an unintended consequence of carbon dioxide emissions from burning fossil fuels.
¥ By pricing in the social and environmental cost of these emissions, we can expedite their reduction. Let’s harness profit greed towards green technology development.
¥ The environmental challenge is to balance the beauty and sacredness of nature with its utility.
ABSTRACT
What are we doing to our climate? The scientific consensus. Tides and temperatures are rising. Since the beginning of the industrial age, emissions from fossil fuel burning have raised carbon dioxide concentrations to 410 ppm. This is 33% higher than in the last million years. This increase is warming our planet via the Greenhouse Effect. At the present rate of carbon dioxide increase, we will reach 800 ppm by 2100. When our earth was at this concentration 40 million years ago, it was so warm that there was no ice. Sea levels were about 300 feet higher than today.
What is climate change doing to us? “The earth and its poor cry out, and we must listen” Pope Francis. Dry regions are drier and wet ones wetter. Wildfires have increased threefold since 1970, storms more violent, floods setting record heights, and glaciers melting. Natural catastrophes are occurring more than twice as frequently as in 1980. Sea levels could rise as high as 18 feet by 2060. Parts of Earth are increasingly uninhabitable, resulting in millions of climate change refugees, CLIMmigration.
What can we do? Religion and science matter. Ethics trumping economics. Let’s yoke our knowledge of climate science with the motivational power of spiritual values. We need to reduce our carbon footprints. We now have the option to purchase green electric cars getting the equivalent of 100 miles per gallon and solar PV panels to lower our electric bills. We can support the Citizen’s Climate Lobby which advocates a revenue neutral carbon production fee resulting in a dividend returned to all. This would stimulate our economy creating millions of jobs and increase the deployment of green solar, wind, and nuclear energy sources. Thorium, in addition to uranium, is a green energy source for the future. Republicans are less afraid of nuclear energy than Democrats.

Understanding earth’s greenhouse
The document discusses the greenhouse effect and how it leads to warming of the Earth. It explains that greenhouse gases like carbon dioxide and methane trap heat in the atmosphere and have increased due to human emissions. Data from ice cores shows a clear correlation between CO2 levels, temperature, and sea level rise over hundreds of thousands of years. While CO2 levels have increased about 40% since the industrial revolution, emissions continue to rise rapidly and could lead to over 2 degrees Celsius of warming with serious consequences if left unchecked.

Turn down the heat final project notes
This document summarizes key points from a course on climate change:
1. We are already experiencing impacts from 0.6-0.8°C of warming and have at least another 0.6-0.8°C committed due to past emissions.
2. Continuing at current emission rates would take us to 450ppm CO2 by 2035, a potential "tipping point" for climate change and ecosystems.
3. Warming of 2°C may be too much and could lead to further warming from feedbacks like melting ice sheets and methane release potentially taking us to 3°C.
Turn down the heat
1) Climate change consequences like storms, droughts and heat waves are already occurring at just 0.8°C of warming.
2) Carbon dioxide levels are on a trajectory to hit 450 ppm by 2030-2035, committing us to around 2°C of warming and severe ocean acidification.
3) Amplifying feedbacks like ice sheet melting, methane releases and reduced Arctic albedo could push warming above 2°C to 3°C or more, levels that may have uncontrollable impacts on the biosphere.
Building the electron economy
This document discusses the need to transition to an "electron economy" to address climate change, energy security, and sustainability issues within the next 20 years.

It outlines a nanotechnology training program with courses on nanomaterials, characterization tools, and fabrication methods. The program aims to reskill both recent graduates and more experienced transitional workers by providing hands-on training on instruments at NASA's Advanced Studies Lab, in order to fill skill gaps in local high-tech industries and keep the innovation workforce competitive.
Energy, carbon, climate, action
- Burning carbon leads to increased atmospheric CO2 in a linear relationship, allowing future CO2 levels to be predicted from carbon emissions data.
- Higher CO2 levels cause radiative forcing that can be calculated using a simple formula, and each additional watt of forcing raises temperatures by 0.66°C due to thermal inertia in oceans.
- Positive climate feedbacks may amplify initial warming, potentially doubling or tripling temperatures for a given CO2 level depending on the feedback strength.
